Dr Witold Bloch is an ARC DECRA fellow at the University of Adelaide, School of Physical Sciences. Dr Bloch is the past recipient of an Alexander von Humboldt post-doctoral fellowship which he carried out in the University of Goettingen and TU Dortmund (Germany). One of his research interests involves the utilisation of metal-organic cages for the development of novel porous nanomaterials. The applications that this research aims to address include gas storage and separation as well as heterogeneous catalysis.

Research in my group focuses on developing the synthesis and studying the properties of porous solids composed of molecular cages. Some of the ongoing projects are listed below:
Crystal engineering of metal-organic cage solids. Molecular solids based on cage compounds have recently emerged as an attractive class of porous materials, owing to their solution processability, synthetic versatility and intrinsic porosity. Our recent work has examined the role that solvent plays in determining the crystal-packing and the overall porosity of several solvatomorphic metal-organic cage solids. We have found that these materials possess varying degrees of structural non-rigidity; some solvatomorphs are stable to solvent exchange while others undergo rapid transformations, leading to on/off porosity properties

Aggregation and assembly of PdnL2n coordination cages. Supramoecular self-assembly is widely utilised in biological systems to assemble increasingly advanced multi-functional architectures from maller subunits. This model is prevalent in multi-enzyme complexes, which are capable of highly-efficient sequential catalytic transformations. My research aims to channel this approach in artificial materials synthesis.

2015 - 2017 Alexander von Humboldt Fellowship for post-doctoral researchers (University of Goettingen and TU Dortmund, Germany)
Project summary: Many functional macromolecules in nature (e.g. enzymes) are multi-component assemblies with an intricate and defined active site. This work focused on increasing the structural complexity of artificial nano-cage receptors, which are commonly simple and symmetrical structures with limited functionality. A new methodology was developed which facilitated the assembly of advanced nano-cage compounds composed of two different but complementary ligands. This approach made it possible, for the first time, to ‘stitch’ together two different functionalities in a single self-assembled cage, without the need of a guest template. This approach was utilised to prepare a variety of mixed-ligand cages including one example in which the cage’s uniquely-shaped cavity facilitated shape recognition of stereoisomeric guests. These findings provide significant insights into the synthesis and structure of discrete metal-organic cages and serve as a platform for the design of more complex and sophisticated artificial receptors.
2017 - 2021 Ramsay Research Fellowship (University of Adelaide)
Project summary: Many pharmaceutical compounds are currently synthesised through multi-step processes that use multiple homogeneous catalysts, resulting in a high level of waste production. This project aims to develop novel porous materials for heterogeneous tandem catalysis by linking nano-cage units into an ordered framework material. The ability of such a material to catalyse chemical reactions in tandem is expected to significantly reduce both the cost and waste associated with industrial chemical syntheses.
Discovery Early Career Researcher Award 2019: Linking Supramolecular Nanocages into Multi-functional Materials (University of Adelaide)
This project aims to advance the complexity of metal-organic materials by ordering discrete nano-cage structures called "metal-organic polyhedra" in a multi-functional porous solid. The project expects to generate critical knowledge in the synthesis of high-performance materials by combining the advantages of metal-organic and dynamic covalent chemistry. The expected outcomes of the project include the development of materials that are able to sequentially catalyse chemical reactions in a single-batch process. This project should deliver benefits for Australia’s emerging chemical manufacturing industry, such as a reduction in the cost, wastage and environmental impact of the chemical manufacturing industry.
